Preparation

1. Remove and discard leg truss from turkey. Pull off and discard any lumps of fat. Remove giblets and neck; discard or reserve for other uses. Rinse turkey inside and out; pat dry. Rub about a third of the guajillo-tamarind glaze inside the cavity. Place turkey, breast up, on a V-shaped rack in a 12- by 17-inch roasting pan; pour remaining glaze into bottom of pan, then pour in 1 cup of water.

3. Roast according to chart, checking turkey every 30 minutes; if juices in bottom of roasting pan threaten to scorch, add 1/2 cup water at a time to pan. When a thermometer inserted through thickest part of breast to the bone registers 155°, about 15 minutes before chart indicates turkey will be done, remove turkey from oven. Brush all over with juices in pan (if liquid is too thick to coat turkey in a thin, even layer, dilute with 1/2 cup more water). Continue roasting until turkey is well browned and thermometer registers 160°, about 15 minutes longer.

4. Transfer turkey to a platter. Let rest in a warm place for 30 minutes before carving. Pour juices in bottom of pan through a fine strainer into a 2-cup glass measure; discard solids and reserve juices for poblano gravy.

Preparation

2. In a 3- to 4-quart pan over medium heat, melt butter. Add chiles and stir for 1 minute. Turn heat to medium-low and whisk in flour until well combined.

3. Whisking chile mixture constantly, slowly pour dripping mixture into pan. Whisk until gravy boils and thickens, 6 to 8 minutes. If gravy is thicker than desired, add a little more broth. Season to taste with salt and pepper. Pour into a gravy boat; serve hot.
